IWROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letters Patent and making part ofxthe same.

To all lwhom it may concern.

Be it known that I, D. H. PAUIhof. De Witt, in the county of Clinton, and State of Iowa, have invented anew and useful Improvement in Oultivators; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in thelart tom'ake and use the same, reference being had tojthe accompanyingdrawings,`= forming part ot' this specification, in which-m .A j

Figure 1 is a side sectional view of 'a portion of a cultivator, having my improvement attached, a: a:,'ig. 2, showing the lineof section. x

Figure 2 is a front -view ofthe same. y

Figure 3 is a detached-viewinf 'a toothed bar, pertaining to the same. l f;

Similar letters of reference indicate like parts'.

This invention relates to a new and useful improvement in cultivators, and has ifor its object the preven v tion of the choking or clogging. of the implement by weeds, stalks, and similar trash.

The invention consists in the application of saws'to the plow or share-standards, in such a manner tha-t the shares or plows are'kept ii'ee from all weedsor trash, thc latter heilig either cut by the action of the saws, or forcedv ott` from the shares or plows.

The frame of-the cultivator may be constructed in any proper manner, and mounted on wheels, in the usual way. These parts are shown in red.

On the front part ot' this frame there is secured, transversely, a' crank-shaft, A, which is operated from the wheels ou which the frame of the machine is mounted'by means of gearing, as shown clearly in fig. 1.

'B represents plow or share-standards, which are attached tc the rear cud of beams, the front ends of the latter being secured by joints to the front cross-bar of'v I over the tops of the plows or shares, and hence, it will be seen that the saws, under the reciprocating motion given them by the crank-shaft, will cut or sever stalks, weeds, or any trash which may catch on the plow or share-standards; or, -if the saws do not cut or sever such trash, they will cast it oifroxn the plows or shares.

I design, in practice, to have supplemental bars, E, attached to one side-- ot' the bars C, the former extending back as far as a little behind the standards B, and having coarse teeth, c, at their lower edges, as shown in iig. 3. This-arrangement insures the stripping of the weeds and trash from the plow or share-standards.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent-'4 The application of reciprocating saws to a cultivap tor, in the manner substantially as shown and dcscribed, for the purpose ot' cutting or'severingiweeds or trash, which may adhere to the plow or share-staud ards, and stripping it from the latter, asset forth,
